But those who deny Our signs - We will progressively lead them [to destruction] from where they do not know. 182 And (for this purpose) I will grant them respite. My design is incontrovertible. 183 Do they not reflect? Their companion is not seized with madness: he is but a perspicuous warner. 184 Or have they not considered the dominion of the heaven and of the earth, and what things God has created, and that it may be their term is already nigh? In what manner of discourse then will they after this believe? 185 For those whom God lets go astray, there is no guide; and He shall leave them in their overweening arrogance, blindly stumbling to and fro. 186 They ask you about the hour, when will be its taking place? Say: The knowledge of it is only with my Lord; none but He shall manifest it at its time; it will be momentous in the heavens and the earth; it will not come on you but of a sudden. They ask you as if you were solicitous about it. Say: Its knowledge is only with Allah, but most people do not know. 187 Say: 'I do not have the power to acquire benefits or to avert harm from myself, except by the Will of Allah. Had I possessed knowledge of the unseen, I would have availed myself of much that is good, and no harm would have touched me. But I am only a warner and a bearer of glad tidings for a nation who believe. 188
